"Anything That Floats" contest. Participants use all their creativity, and the results are unconventional to say the least. This lab will stimulate creative thinking as students design and build their own boats to test for buoyancy.
Materials: Newspapers Turkey roaster (or other large pan) Water Miscellaneous materials for boat building (e.g., toothpicks, cork, Styrofoam, construction paper, aluminum foil, wood, tin, plastic) Large plastic container to hold building supplies Paper towels Sponges Student Lab Sheet
Preparation: Cover the lab area with newspaper. Fill a turkey roaster (or similar pan) with water. Put the building materials in a plastic container. Have sponges and paper towels handy so that students can clean up at the conclusion of the lab. Duplicate Student Lab Sheet.
Answers to Student Lab Sheet:
1. The boat floats because the density of the boat equals the amount of water displaced. 2. Answers will vary. 3. Answers will vary. Students should be able to justify their answers.
Super Scientist Activities:
1. Poems will vary. 2. The boat would float higher in salt water. Although the paragraphs will vary, all should include the concept that ocean water is more dense than fresh water because ocean water contains salt. Due to salt water's greater density, less of it is displaced (moved) when the object is immersed. As a result, the object floats higher in salt water than in fresh water.
Anchors AweighStudent Lab Sheet Are you ready to go boating? Do you have a boat? In this lab, you will design a boat and then test it to see if it floats. You better have your life jacket on...just in case!
Materials: Newspapers Large pan with water Container full of boat-building materials Paper towels Sponges Pencil
Procedures:
1. Think about a design for your boat. 2. Use the materials to build the boat you designed in your mind. 3. Test the boat in the pan of water. 4. Modify (change) your boat until it floats safely. 5. Draw a picture of your boat. 6. Take the boat apart. 7. Clean up the learning center.
Questions To Answer: 1. Why does your boat float? 2. What did you use to make your boat stable? 3. Would your design be practical to use for a real boat? Why or why not?
Super Scientist Activities: 1. Write a poem about sailing in a boat. 2. Would your boat float higher in salt water or fresh water? Write a paragraph that explains why.
